什么是数码相机摄影知识点？英文双语对照

光圈

相机镜头内有一组重叠的金属叶片，其所围成的孔径大小和开放的时间决定了一次成相 的暴光量，也产生了相机的光圈和速度。

光圈英文名称为Aperture.光圈是一个用来控制光线透过镜头，进入机身内感光面的光 量的装置，它通常是在镜头内。

表达光圈大小我们是用F值。光圏卩值=镜头的焦距/镜头口径的直径，从以上的公式

可知要达到相同的光圏F值，长焦距镜头的口径要比短焦距镜头的口径大。完整的光圏值系

快门

相机的快门速度仍需手动,主要包括以下，由慢而快，1、1/2、1/4、1/8、1/15、1/30、1/60、 1/125、1/250、1/500、1/1000秒，在一些更专业的相机中，还有比这些更长或更短的快 门速度设置。同样的，快门速度每向上或向下跳一格.暴光量加倍或减半、

快门类型

快门英文名称为Shutter.快门是相机上控制感光片有效曝光时间的一种装置。

目前的数码相机快门包括了电子快门、机械快门和B门。

完善的快门通常必须具备以下几个方面的作用:

一、 是必须貝备有能轄准确调控曝光时间的作用，这一点是照相机快门的最基本的作用：

二、 是必須具备有足够高的快门速度.以利于拍摄高速动动全或有效控制景深：

三、 是必须具有长时间曝光的作用，即应设有TTJ或门：

四、 是具有闪光同步拍摄的功能：

五、 是具有自拍的功能，以便于ri拍或在无快门线的情况卜进行长时冋哗光时.使快门开启.

快门速度

感光度iso

胶片的主要参数是指胶片的感光度，用ISO值来标示(International Standards Organization的简称)。ISO值越大，胶片/感光传感器的感光度越高，越容易暴光。

曝光模式

嚕光英文名称为Exposure.曝光模式即计算机采用fl然光源的模式，通常分为多种.包 括：快门优先、光圏优先、手动曝光、AE锁等模式.照片的好坏与曝光虽有关，也就是说 应该通多少的光线使C8能够得到清晰的图像.曝光量与通光时间（快门速度决定），通 光面枳（光圏大小决定）有关。

感光器件

提到数码相机，不得不说到就是数码相机的心脏一感光器件。与传统相机相比，传统 相机使用”胶卷"作为其记录信息的载体，而数码相机的''胶卷"就是其成像感光器件，而且是 与相机一体的，是数码相机的心脏。感光器是数码相机的核心，也是最关键的技术。数码相 机的发展道路，可

Aperture

There is the metallic blade of a group of jackknives inside camera camera lens, the bore diameter size that its surround and open time decided to become the exposure quantity of the photograph, also produced the aperture of camera and rate.

Aperture English name is Aperture. Aperture is one uses control light to pass through camera lens, enter the plant of the smooth quantity of sensitive face inside airframe, it is to be inside camera lens normally.

Expressive aperture size we are to use F value. The focal length of camera lens of = of value of smooth Piao / the diameter of camera lens caliber, from the formula of above

Knowable should reach value of same smooth F, the line of action that the caliber of camera lens of long focal distance wants to compare camera lens of short focal distance is large. Complete smooth is worth a department

Shutter

The shutter speed of camera still needs a hand to move, basically include the following, by slow and fast, 1, 1/2, 1/4, 1/8, 1/15, 1/30, 1/60, 1/125, 1/250, 1/500, 1/1000 second, in a few more professional camera, still have longer than these or shorter shutter speed setting. Same, shutter speed every up or jump downward one case. Exposure is measured double or halve,

Fast class

Shutter English name is Shutter. Shutter is plate of the control on camera a kind of device of significant time of exposure.

Current digital camera shutter included electronic shutter, mechanical shutter and B door.

Perfect shutter must have the effect of the following respects normally:

One, be must Zuo stock can the action of time of exposure of Zuo accurate adjusting control, this are the mainest effect of camera shutter:

2, it is to need Zuo has stock enough high shutter rate. Use depth of field of complete or effective control at filming high speed moves with benefit:

3, it is the effect that must have a time exposure, should set TTJ or door namely:

4, it is the function that has flashy synchronism to film:

5, it is to have the function that takes oneself, with facilitating Ri is patted or the when undertaking length is predicted in the circumstance that does not have shutter release when clang light. Make shutter open.

Shutter speed

Speed Iso

The main parameter of film is the speed that points to film, with ISO the value comes indicative (the abbreviation) of International Standards Organization. ISO value is greater, film / the speed of sensitive sensor is higher, jump over easy exposure.

Exposure mode

Name of smooth English is Exposure. Exposure mode namely the computer uses Fl like that the mode of illuminant, normally cent is a variety of. Include: Shutter is preferential, smooth preferential, hand moves the mode such as lock of exposure, AE. Although the stand or fall of the photograph and exposure are concerned, the light that how much should connect that is to say makes C8 can get clear picture. Light exposure and the time that connect light (shutter speed decides) , trifoliate orange of the face that connect light (smooth size decides) about.

Sensitive parts of an apparatus

Mention digital camera, must the heart that respecting is digital camera one sensitive parts of an apparatus. Compare with traditional camera photograph, traditional camera is used " the carrier that film " regards his as record information, and the '' film " of digital camera is his into resemble sensitive parts of an apparatus, and be with camera an organic whole, it is the heart of digital camera. Sensitive implement the core that is digital camera, also be the most crucial technology. The development road of digital camera, but
